Abstract

Das Personenschutzfunkgerät wird von der zu schützenden Person an einer Haltevorrichtung, beispielsweise eingebaut im Absatz eines Arbeitsschuhs, mitgeführt und enthält einen von einer geräteeigenen Stromquelle (10) versorgten Sender (23), einen Empfänger (21) und eine Antennenanordnung (21, 24). Um bei großer Reichweite des Senders eine hohe betriebliche Zuverlässigkeit und eine lange wartungsfreie Einsatzdauer zu gewährleisten, ist die geräteeigene Stromquelle ein aufladbarer Akkumulator (10), der von einer einen piezoelektrischen Wandler (12) enthaltenden Generatoranordnung während des betrieblichen Einsatzes des Geräts aufladbar ist. Der piezoelektrische Wandler (12) ist im Arbeitsschuh derart angeordnet, daß er vom Gewicht der den Arbeitsschuh tragenden Person beaufschlagt ist und dadurch den Gewichtsdruck in elektrische Energie umwandelt.The personal protection radio device is carried by the person to be protected on a holding device, for example installed in the heel of a work shoe, and contains a transmitter (23) supplied by a device-specific power source (10), a receiver (21) and an antenna arrangement (21, 24). In order to ensure high operational reliability and a long maintenance-free period of use when the transmitter has a long range, the device's own power source is a rechargeable accumulator (10) which can be charged by a generator arrangement containing a piezoelectric transducer (12) during the operational use of the device. The piezoelectric transducer (12) is arranged in the work shoe in such a way that it is acted upon by the weight of the person wearing the work shoe and thereby converts the weight pressure into electrical energy.

Description

Die Erfindung bezieht sich auf das Gebiet des Personenschutzes und der Personenortung, insbesondere auf ein Personenschutz­funkgerät, das von der zu schützenden Person an einer Halte­vorrichtung mitgeführt wird und einen von einer geräteeigenen Stromquelle versorgten Sender und eine Antennenanordnung ent­hält.The invention relates to the field of personal protection and location, in particular to a personal protective radio device that is carried by the person to be protected on a holding device and contains a transmitter supplied by a device-specific power source and an antenna arrangement.

Dem Personenschutz oder Arbeitsschutz dienende Funkanlagen lassen sich ihrer Funktion entsprechend in zwei Kategorien einteilen. Bei der einen Kategorie dient ein eigenerregter, in der Regel permanent aktiver Sender, der von der zu schützenden Person entweder in einem Schuh, einem Gürtel oder bei Einsatz in Untertagebetrieben in der Kopfleuchte mitgeführt wird, zur Makierung der Person (DE-P 20 26 167). Der permanent aktive Sender strahlt ständig ein Hochfrequenzsignal aus, das bei Empfang durch eine im Gefahren- oder Kontrollbereich in der Regel stationär angeordnete Empfangsantenne einen Signal­empfänger und die mit diesem verbundene Schalteinrichtung betätigt. Aufgrund des permanenten Energieverbrauchs ist selbst bei modernen, leistungsstarke Batterien die Betriebs­dauer begrenzt. Die Stromquelle und deren Energieverbrauch bildet bei längerem, kontinuierlichem Betrieb ein erhebliches Betriebsrisiko, insbesondere bei Geräten, die dem Personen­schutz und auch der Ortung von verschütteten moder eingeschlos­senen Personen in Untertagebetrieben, Baubetrieben oder auch in lawinengefährdeten Bereichen dienen.Radio systems serving personal protection or occupational safety can be divided into two categories according to their function. In one category, a self-excited, usually permanently active transmitter, which is carried by the person to be protected either in a shoe, a belt or in the head lamp when used in underground operations, serves to mark the person (DE-P 20 26 167 ). The permanently active transmitter continuously emits a high-frequency signal which, when received by a receiving antenna which is generally stationary in the danger or control area, actuates a signal receiver and the switching device connected to it. Due to the permanent energy consumption, the operating time is limited even with modern, powerful batteries. The power source and its energy consumption constitute a considerable operational risk in the case of prolonged, continuous operation, in particular in the case of devices which serve to protect people and also to locate spilled, moderately trapped people in underground operations, construction operations or in areas where there is a risk of avalanches.

Bei der zweiten Kategorie handelt es sich um sogenannte passi­ve Gefahrensignalgeber ohne eigene Energiequelle. Der Gefah­rensignalgeber enthält einen Sendeempfänger, der in einem vorgegebenen Sendebereich eines Senders durch eine bestimmte Sendefrequenz erregt wird und ein Antwortsignal auf einer anderen Frequenz ausstrahlt. Ein Gefahrensignalempfänger ent­wickelt aus der Antwortfrequenz Alarm- oder Abschaltsignale. Der Vorteil dieser Geräte liegt in der Unabhängigkeit des Sendeempfängers von einer Energieversorgung. Der wesentliche Nachteil rein passiver Sendeempfänger liegt bekanntlich in ihrer zu geringen Reichweite. Aufgrund dieses Nachteils ist der Einsatz rein passiver Sendeempfänger zur Markierung ver­schütteter Personen insbesondere im Untertagebetrieb zu risi­koreich.The second category is a so-called passive hazard signal generator without its own energy source. The hazard signal transmitter contains a transceiver which is excited by a specific transmission frequency in a predetermined transmission range of a transmitter and emits a response signal on another frequency. A hazard signal receiver develops alarm or shutdown signals from the response frequency. The advantage of these devices is the independence of the transceiver from an energy supply. The essential As is well known, the disadvantage of purely passive transceivers is that their range is too short. Because of this disadvantage, the use of purely passive transceivers for marking spilled people is too risky, especially in underground operations.

Der Erfindung liegt die Aufgabe zugrunde, ein Personenschutz­funkgerät der eingangs genannten Art zu schaffen, das die Vorteile einer großen Reichweite, einer kompakten Bauweise, einer hohen betrieblichen Zuverlässigkeit und einer langen wartungsfreien Einsatzdauer vereinigt.The invention has for its object to provide a personal protective radio device of the type mentioned, which combines the advantages of a large range, a compact design, high operational reliability and a long maintenance-free period of use.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die geräteeigene Stromquelle ein wiederaufladbarer Akkumulator ist und daß der Akkumulator mit einer Generatoranordnung solcher Ausbildung verbunden ist, daß er von der Generatoranordnung während des betrieblichen Einsatzes des Geräts aufgeladen werden kann.This object is achieved in that the device's own power source is a rechargeable battery and that the battery is connected to a generator arrangement such that it can be charged by the generator arrangement during operational use of the device.

Bei der Erfindung werden bewährte Akkumulatorzellen benutzt, die eine praktisch gleichbleibende und von den Umständen ihres Einsatzes weitgehend unabhängige Spannungs- und Energieabgabe­gewährleisten. Ihre Betriebsdauer wird von der Generatoranord­nung durch automatisches Aufladen im betrieblichen Einsatz verlängert. In herkömmlichen Personenschutzfunkgeräten werden die Batterien im betrieblichen Einsatz ständig entladen. Die Erfindung nutzt daher die bekannterweise große Reichweite von eigenversorgten Personenschutzfunkgeräten aus, erhöht aber deren Zuverlässigkeit und deren Betriebsdauer durch ständige betriebliche Aufladung. Der Einsatzbereich der Personenschutz­funkgeräte wird dadurch nicht unerheblich erweitert und deckt alle Markierungs- und Ortungsaufgaben insbesondere unter den erschwerten Umständen in untertägigen Gewinnungsbetrieben ab. Verschüttete und eingeschlossene Personen können daher bei Mitführung des neuen Personenschutzfunkgerätes auch aus großen Distanzen geortet und gegebenenfalls rasch befreit werden.Proven accumulator cells are used in the invention, which guarantee a practically constant voltage and energy output that is largely independent of the circumstances of their use. The generator arrangement extends its operating time through automatic charging during operational use. In conventional personal protective radio devices, the batteries are constantly discharged during operational use. The invention therefore makes use of the known long range of self-supplied personal protective radio devices, but increases their reliability and their operating time through constant operational charging. The area of application of the personal protection radio equipment is thereby expanded considerably and covers all marking and location tasks, especially under the difficult circumstances in underground mining operations. Spilled and trapped people can therefore Carrying the new personal protection radio can also be located from great distances and, if necessary, quickly released.

In bevorzugter Weiterbildung der Erfindung weist die Genera­toranordnung einen Druckwandler, insbesondere einen piezoelek­trischen Wandler auf. Dieser ist im Sohlen- oder Absatzbereich eines Schuhs oder Stiefels derart eingebaut, daß er den Soh­len- oder Absatzdruck beim Gehen der zu schützenden Person teilweise aufnimmt und in eine Spannung zur Aufladung des Akkumulators umsetzt. Derartige piezoelektrische Wandler kön­nen aber auch in anderen Kleidungsstücken, so z.B. an der Schnalle eines sogenannten Funksicherheitsgürtels angeordnet werden. In dieser Ausführung ist die druckempfindliche Membran der piezoelektrischen Zelle an der Innenwand der Gürtelschnal­le derart angeordnet, daß sie durch die Bauchmuskeln (bei­spielsweise beim Atmen) einem sich ändernden und damit in eine Spannung umsetzbaren Druck ausgesetzt ist.In a preferred development of the invention, the generator arrangement has a pressure transducer, in particular a piezoelectric transducer. This is installed in the sole or heel area of a shoe or boot in such a way that it partially absorbs the sole or heel pressure when the person to be protected is walking and converts it into a voltage for charging the battery. Such piezoelectric transducers can also be used in other items of clothing, e.g. to be placed on the buckle of a so-called radio safety belt. In this embodiment, the pressure-sensitive membrane of the piezoelectric cell is arranged on the inner wall of the belt buckle in such a way that it is exposed to a changing pressure which can be converted into tension by the abdominal muscles (for example when breathing).

Die im Gerät befindlichen, beispielsweise als kleine Knopf­zellen ausgebildeten Akkumulatorzellen benötigen eine bestimm­te Auflade-Mindestspannung. Diese Mindestspannung kann unter bestimmten Umständen, so beispielsweise bei Anordnung des Druckwandlers an der Gürtelschnalle, nicht von einer einzigen piezoelektrischen Zelle aufgebracht werden. Daher sieht die Erfindung vor, daß mehrere piezoelektrische Zellen parallel und/oder in Reihe geschaltet sind.The battery cells located in the device, for example in the form of small button cells, require a certain minimum charging voltage. Under certain circumstances, for example when the pressure transducer is arranged on the belt buckle, this minimum voltage cannot be applied by a single piezoelectric cell. The invention therefore provides that a plurality of piezoelectric cells are connected in parallel and / or in series.

In alternativer Ausführung kann die Generatoranordnung einen durch Bewegungsenergie erregbaren induktiven Wandler mit we­nigstens einem Magnetkern und einer diesen umgebenden Indukti­onsspule aufweisen, wobei eine der aus Magnetkern und Indukti­onsspule bestehenden Komponenten fest und die andere Komponen­te zur Erzeugung einer Induktionsspannung beweglich in der Haltevorrichtung des Personenschutzfunkgeräts angeordnet ist.In an alternative embodiment, the generator arrangement can have an inductive transducer which can be excited by kinetic energy and has at least one magnetic core and an induction coil surrounding it, one of the components consisting of a magnetic core and an induction coil being fixed and the other component for generating an induction voltage being movably arranged in the holding device of the personal protection radio.

Die Induktionsspannung wird über eine Gleichrichterschaltung an den Akkumulator angelegt, um sie zur Aufladung des Akkumu­lators gleichzurichten.The induction voltage is applied to the accumulator via a rectifier circuit in order to rectify it for charging the accumulator.

Die Generatoranordnung kann entweder alternativ oder zusätz­lich zu den zuvor genannten Energieerzeugern eine Induktions­spule aufweisen, in der durch Verkettung mit einem äußeren Feld ein Strom zur Aufladung des Akkumulators induzierbar ist. Im Untertageeinsatz kann ein solches Feld beispielsweise in einer Kontrollstation aufgebaut sein und beim Durchschreiten einer Kontrollzone gegebenenfalls in Verbindung mit einer Prüfung des Personenschutzfunkgeräts wirksam werden.As an alternative or in addition to the aforementioned energy generators, the generator arrangement can have an induction coil in which a current for charging the rechargeable battery can be induced by interlinking it with an external field. In underground use, such a field can be set up, for example, in a control station and, if necessary, become effective when passing through a control zone in connection with a test of the personal protection radio.

Zur Vermeidung von Überspannungen bei der Aufladung des Akku­mulators weist die Generatorschaltung in Weiterbildung der Erfindung eine Spannungs-Verstärker und/oder Begrenzungs­schaltung auf.In order to avoid overvoltages when charging the accumulator, the generator circuit in a development of the invention has a voltage amplifier and / or limiting circuit.

Im folgenden wird die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. In der Zeichnung zeigen:

  • Fig. 1 ein schematisches Blockschaltbild eines Ausfüh­rungsbeispiels des erfindungsgemäßen Personen­schutzfunkgeräts; und
  • Fig. 2 eine Teilansicht auf einen in Untertagebetrie­ben verwendeten Arbeitsschuh, bei dem das er­findungsgemäße Personenschutzfunkgerät im Schuhabsatz eingebaut ist.
The invention is explained in more detail below with reference to an embodiment shown in the drawing. The drawing shows:
  • Figure 1 is a schematic block diagram of an embodiment of the personal protection radio device according to the invention. and
  • Fig. 2 is a partial view of a work shoe used in underground operations, in which the personal protection radio device according to the invention is installed in the shoe heel.

Das in Fig. 1 als Blockschaltbild dargestellte Personenschutz­funkgerät besteht aus einem Stromversorgungsteil 1 und einem Verbraucher 2.The personal protection radio device shown as a block diagram in FIG. 1 consists of a power supply part 1 and a consumer 2.

Die Stromversorgung 1 weist als Stromquelle einen aufladbaren Akkumulator 10 in Form beispielsweise einer im Handel erhält­lichen Knopfzelle und eine Generatoranordnung 11 auf. Letztere ist so ausgebildet und mit dem Akkumulator 10 verbunden, daß sie den Akkumulator mit der erforderlichen Ladespannung aufla­den kann. Die Generatoranordnung 11 weist eine Wandler 12 auf, der so ausgebildet ist, daß er entweder auf ihn wirkende Druckenergie oder Bewegungsenergie oder auch die von außen über ein geeignetes Feld auf ihn wirkende Energie in elektri­sche Energie zur Aufladung des Akkumulators 10 umzusetzen vermag. Bei einem bevorzugten Ausführungsbeispiel ist der Wandler als piezoelektrischer Wandler ausgebildet, der in einer geeigneten Drucktasche (Fig. 2) im Absatzbereich eines Arbeitsstiefels angeordnet und dem Fersendruck des Benutzers im Betrieb ausgestzt wird. In alternativer Ausführung kann der Wandler 12 aber auch als induktiver Bewegungswandler aus­gebildet sein, bei dem ein magnetischer Kern in einer geeigne­ten Induktionsspule angeordnet ist und durch Relativbewegung zur Induktionsspule in letzterer eine zur Aufladung des Akku­mulators 10 dienende Induktionsspannung erzeugt. Die zur Aus­lösung der Relativbewegung zwischen magnetischem Kern und Induktionsspule erforderliche Relativbewegung wird durch das Bewegungsspiel der das Gerät tragenden Person während der Arbeit hervorgerufen.The power supply 1 has a rechargeable battery 10 in the form of, for example, a commercially available button cell and a generator arrangement 11 as the current source. The latter is designed and connected to the accumulator 10 so that it can charge the accumulator with the required charging voltage. The generator arrangement 11 has a converter 12 which is designed such that it is able to convert either pressure energy or kinetic energy acting on it or the energy acting on it from outside via a suitable field into electrical energy for charging the accumulator 10. In a preferred embodiment, the transducer is designed as a piezoelectric transducer, which is arranged in a suitable pressure pocket (FIG. 2) in the heel area of a work boot and is subjected to the user's heel pressure during operation. In an alternative embodiment, the transducer 12 can also be designed as an inductive motion transducer, in which a magnetic core is arranged in a suitable induction coil and generates an induction voltage which serves to charge the accumulator 10 by relative movement to the induction coil in the latter. The relative movement required to trigger the relative movement between the magnetic core and the induction coil is caused by the movement play of the person wearing the device during work.

Dem Wandler 12 nachgeschaltet ist eine in Fig. 1 mit Regler bezeichnete Komponente 13. Der Regler kann als Spannungsver­stärker ausgebildet sein, um die im Wandler 12, insbesondere in einem rein induktiven Wandler, erzeugte Spannung auf das für die Aufladung des Akkumulators 10 erforderlich Spannungs­niveau anzuheben. Bei Ausführung des Wandlers als piezoelek­trische Zelle oder als Reihenschaltung mehrerer piezoelektri­scher Zellen kann die im Wandler erzeugte Spannung die notwen­ dige Ladespannung unter Umständen deutlich übersteigen. In diesem Falle wirkt der Regler 13 vorzugsweise als Spannungsbe­grenzer. Zur Generatoranordnung 11 gehört ferner ein Gleich­richter 14, der zum Regler und Wandler in Reihe liegt und eine Entladung des Akkumulators 10 über den Generatorstromzweig verhindert. In dem dargestellten Ausführungsbeispiel ist außerdem eine Zenerdiode 15 zur Begrenzung etwaiger Auflade-­-Überspannungen vorgesehen.The converter 12 is followed by a component 13 designated as a controller in FIG. 1. The controller can be designed as a voltage amplifier in order to raise the voltage generated in the converter 12, in particular in a purely inductive converter, to the voltage level required for charging the accumulator 10 . When the transducer is designed as a piezoelectric cell or as a series connection of several piezoelectric cells, the voltage generated in the transducer may be necessary under certain circumstances significantly exceed the charging voltage. In this case, the controller 13 preferably acts as a voltage limiter. The generator arrangement 11 also includes a rectifier 14, which is in series with the regulator and converter and prevents the accumulator 10 from being discharged via the generator current branch. In the exemplary embodiment shown, a Zener diode 15 is also provided to limit any charging overvoltages.

Der Verbraucher 2 ist an die beiden Pole 16, 17 der Stromver­sorgung 1 angeschaltet. Er weist einen Empfänger 20 mit Emp­fangsantenne 21, einen Oszillator 22, einen Sender 23 mit Sendeantenne 24 und einen vorzugsweise elektronischen Schalter 25 auf. Der Schalter 25 ist dem beschriebenen Ausführungsbei­spiel derart angeordnet, daß der Verbraucherstromkreis im Ruhezustand offen ist, also keine Entladung über den Verbrau­cher 2 stattfindet. Zu diesem; Zweck ist der Schalter 25 als Schließer ausgebildet, der nur bei geeigneter Ansteuerung über den Empfänger 20, d.h. bei Empfang eines geeigneten äußeren Rufsignals beispielsweise bei einer vorgegebenen Frequenz geschlossen wird. Ist der Schalter 25 geschlossen, so werden der Oszillator und der Sender an die Stromversorgung 1 ange­schaltet und entnehmen dem Akkumulator 10 die zur Entwicklung eines geeigneten Sendesignals erforderliche elektrische Ener­gie. Dieses Signal ist in der Praxis so stark, daß es zum Zwecke der Ortung von Verschütteten oder Eingeschlossenen noch etwa 10 m Haufwerk zuverlässig durchdringen kann. Bei diesem Ausführungsbeispiel ist der Verbraucher im normalen betriebli­chen Einsatz stummgeschaltet und verbraucht keine Akkumulator­energie. Erst Bei Aufruf und über die Dauer des Empfangs eines äußeren Aufrufsignals ist der Sender 23 aktiv und sendet sein Signal über die Sendeantenne 24. In alternativer Ausführung können die Komponenten 20, 22 und 23 auch mit einer bestimmten reduzierten Menge an elektrischer Energie gespeist werden, um einen permanenten Sendebetrieb bei niedriger Sendeleistung zu gewährleisten. In diesem Falle sollte der Schalter 25 eine Handbetätigung haben, die den Verbraucher außerhalb der Be­triebszeiten, d.h. im Ruhezustand, vom Stromversorgungsteil 1 abtrennt.The consumer 2 is connected to the two poles 16, 17 of the power supply 1. It has a receiver 20 with a receiving antenna 21, an oscillator 22, a transmitter 23 with a transmitting antenna 24 and a preferably electronic switch 25. In the exemplary embodiment described, the switch 25 is arranged such that the consumer circuit is open in the idle state, that is to say there is no discharge via the consumer 2. To this; The purpose of the switch 25 is designed as a closer, which is closed only when the trigger 20 is appropriately activated, ie when a suitable external call signal is received, for example at a predetermined frequency. If the switch 25 is closed, the oscillator and the transmitter are connected to the power supply 1 and take the electrical energy required to develop a suitable transmission signal from the accumulator 10. In practice, this signal is so strong that it can reliably penetrate about 10 m of piles for the purpose of locating buried or trapped people. In this exemplary embodiment, the consumer is muted in normal operational use and does not consume battery energy. Only when a call is received and for the duration of the reception of an external call signal is the transmitter 23 active and sends its signal via the transmit antenna 24. In an alternative embodiment, the components 20, 22 and 23 can also be supplied with a certain reduced amount of electrical energy to ensure permanent transmission with low transmission power. In this case, the switch 25 should have a manual actuation which disconnects the consumer from the power supply part 1 outside the operating times, ie in the idle state.
